When got the truck it said the average was 17.9, But I think that was alot of highway driving. I reset the average and am doing alot of intown driving (60 miles) with a new average of 15.3 mpg. I was wondering if anyone has tried or is using some aftermarket parts to improve there mileage? I want to see if a coldair filter or something easy to "bolt on" and get a good improvement? Thanks for the info, Eric
